摘要：
We fabricated few-layered MoSe2 nanosheets via the simple ultrasonic-assisted liquid phase exfoliation (UALPE) method. Typical characterizations and testing were exploited to confirm the nonlinear absorption properties of MoSe2 nanoflakes. A passively Q-switched Nd:YVO4 laser emitting 1 mu m wavelength was demonstrated with the as-prepared MoSe2 saturable absorber (SA). The stable pulses were generated with a maximum output power of 215 mW and a shortest pulse width of 192 ns. The experimental data provided a solid base for the photonics applications of MoSe2 nanomaterials.
